Nobile Twintip Fins Includes: 4 pack of Nobile Fins Please note: For G 10 30mm fins come with regular screws as pictured. 30mm fins do not accept thumb screws. G10 Fins Nobile G10 fins are made of stiff glass composite which guarantees high durability. This material makes the connection between fins and the board very strong, while keeping the low flexibility of the fins. This ensures the high level of control when riding. Nobile G10 fins are compatible with the tool-free “Click&Go” mounting standard and can be used interchangeably with PA fins. The ultra orange color of the fins is superbly visible from the distance, so losing your precious kiteboard in the water is almost impossible. CLICK’N’GO PA GF33 Nobile fins are produced in „Click&Go” tool-free mounting standard. It takes just a few seconds to mount/dismount fins with yourbare hands. A screwdriver is no longer necessary. We redesigned the mounting system to provide a stronger connection between thefin and the board. It’s also easier and faster to mount and demount the fins. Sizes (mm): 20, 40, 55 Nobile PA GF33 fins are made of 33% glass reinforced PA (Polyamide). Fins are made in extremely highly-visible „ultra orange” to let you know where did you drop yo ur precious kiteboard. It features the same durability as G10 Epoxy but is much lighter. 33% glass reinforced PA fins become a standard in all Nobile boards.1. DURABILITYPolyamide (PA) is light and very durable constructional material, used also in aerospace and machinery industry for production the parts. It is widely known for its light weight and extreme durability. Furthermore, our Polyamide fins are reinforced with fiberglass (33%).2. WEIGHTPolyamide fins feature the same durability and wear resistance as the G10 Epoxy, but are lighter.3. PERFORMANCEThe injection molding technology, used in production of our Polyamide fins, helps to gain fully repeatable hydrodynamic profile. Such profiled shape improves the connection between the fin and the kiteboard. It reduces the water drag by 5 per cent and increases the kiteboard speed. The surface adherence of polyamide fin is 40 per cent better. It results with stronger fin-to-kiteboard connection and greater stability during the ride.4. ECOLOGYPolyamide fins are made in EU with fully recyclable materials
